I wish this helpful for you I don't know why but... If you simply add something to the secnod page and the problem goes away.
code :
<Grid>
    <TextBlock Text="second" />
</Grid>
private async void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
    await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => Frame.Navigate(typeof(second)));
}

Windows Phone 7.1 application quits without throwing any exception

I think the issue was by ths following , Thank you Stephen for you reply. I was still unable to catch any exception with your proposed changes, however, your answer helped me to better understand what is going on behind the curtain. So thanks again for that.
I finally managed to get rid of all the "silent" exceptions that caused the application to - almost half the time - quit randomly shortly after the start. To my surprise it was perhaps not caused by any code of mine, but could be originated in the DataContext class. How come? In my application I have been using two different connection strings:
code :
/* with DeferredLoadingEnabled = false; ObjectTrackingEnabled = true; */
private const string Connection = "Data Source=isostore:/MyDatabase.sdf;max buffer size=1024;max database size=512;";

/* with DeferredLoadingEnabled = false; ObjectTrackingEnabled = false; */
private const string ConnectionReadOnly = Connection + "File Mode = read only;";

help you fix your problem It is possible, for example you can make your eventhandler public and static:
code :
public static void StaticButton_Click(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Event from App.xaml.cs!");
}
// ten at any Page you can subscribe like this:
myButton.Click += App.StaticButton_Click;
public void Button_Click(object sender, RoutedEventArgs e)
{
    MessageBox.Show("Event from App.xaml.cs!");
}
// then you can subscribe like this:
myButton.Click += (App.Current as App).Button_Click;

hop of those help? This is due to spaces in the namespace or in the project name. There has always been a problem surrounding this scenario. I thought Microsoft fixed this particular problem :0/

I hope this helps . I don't believe that the appbar should be a child of the grid element and I am not sure that you are using the correct format for a appbar. The correct way would be something similar to below:
code :
<Page
    x:Class="MainStream.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MainStream"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

    <Grid>
        <Image Grid.RowSpan="2" Stretch="None" Source="/img/sfondo.png" VerticalAlignment="Top" HorizontalAlignment="Center"/>
        <FlipView x:Name="flipView1" Width="480" Height="270" Margin="0,10,0,0" VerticalAlignment="Top" BorderBrush="Black" BorderThickness="1">
            <Image Width="480" Height="270" Stretch="UniformToFill"/>
            <TextBlock FontFamily="Segoe UI" FontSize="26.667" Foreground="#CCFFFFFF" Padding="15,20"/>
        </FlipView>
   </Grid>

    <Page.BottomAppBar>
        <CommandBar Opacity="1">
            <AppBarButton x:Name="AddAppBarButton" Label="add" Icon="Add"  />
            <CommandBar.SecondaryCommands>
                <AppBarButton x:Uid="SecondaryButton1" x:Name="SecondaryButton1" Label="secondary command 1" />
                <AppBarButton x:Uid="SecondaryButton2" x:Name="SecondaryButton2" Label="secondary command 2" />
            </CommandBar.SecondaryCommands>
        </CommandBar>
    </Page.BottomAppBar>

</Page>
